    (54) Control unit for a rotatable platform for a three-axle articulated vehicle


    (57) The present invention relates to a control unit of a rotatable platform for a three-axle articulated vehicle which comprises a pneumatic circuit (20) connected to a source of pressurized fluid (21) and to a braking element (5) arranged at the fifth wheel or rotating platform (7) of the articulated vehicle. The peculiarity of the invention resides in that the braking element is constituted by a disk brake (5) which has a braking disk (6) associated with the center of the fifth wheel (7) and rigidly associated with the rear body (2) of the vehicle, and a braking caliper (16) which acts on the braking disk (6) and is rigidly associated with the front body (1) of the vehicle. The pneumatic circuit actuates the braking caliper (16).
